Fuel-oil burner



FUEL OIL BURNER Filed Nov. 2. 1922 2 sheeshee'b l ranged therein,

casing; 24, having a valve (not shown) arcontrolled by a valve handie 25. l pipe 2h forming a part of the tting 2l is connected to the valve casing. This pipe has relatively small opening 2, communicating with the interior or" the iit ting adjacent the jet pipe 2%. A nozzle 28 is arranged on the outer end of the burner pipe being connected thereto oy fitting 29.

As shown, the outlet end of the nozzle of the main burner pipe is arranged at the front of the burner casing, whereby the Haine is projected beyond the burner casing. An auxiliary burner of similar construction is provided for the purpose of heating the oil retort and the fluid 'ireheating chamber.

As shown, branch pipes 30 and 3l are conneoted to the pipes 13 and l5, respectively, the fluid ipe being connected to a valve casing 32, .airinga valve 33 arranged there- A pipe 34 is connected to the vali/epasing and this pipe is provided with a jet pipe 35, ar'anged therein. A plug 86 prevents communication between the vulve casing and the pipe 34. The end of the iet pipe projects int/o a burner pipe 3T. lfhe auxiliary oil pipe 31. comnuinicates with a valve casing 38 which is in turn connected to a pipe 39, leading into the burner pipe adjacent the jet nine 35.

In operation, air or steam is delivered to the preheatingr chamber 5 through pipe l2 and oil is delivered to the retort 7 through pipe 14. The fluid in the preheating chamber is heated to a very high temperature by heat of the auxiliary burner 37. The oil delivered to the retort is under pressure andis heated to a temperature above its normal boiling point but below the boiling point of the oil at the pressure employed. l. find it advantageous to heat Vthe' oil in the retort to a temperature iust below its boiling point at the pres.- ire employed whereby the oil is maintainec in a liquid slate by the pressure. The preheated fluid passes through the pipe 13 to the valve casing;r 1G, and thence to the jet pipe 22. Passage oit thc fluid tl'irough the jet pipe heat.' the surface of this pipe to a high temperature. The oil from the retort is projected throrudi thc pipe 26 against` the surface ot the jot pipo and due to the high degfrcc, oi" hcut thcrciu. is imulcdiutcly flushed into vapor l'orm. The projection of thc oil against this surface torcthcr with the high dcgjrco oi' heat cm-y ploycd, causcs a complete brcul ii|, r up of thc oil into minuto particlcs and insures complctc vapor-ization. ll will bc noted that tho oil dclivcrcd into thc fitting 21 :il :in angle causcs it lo (low rearwardly u short distance bci'orc it is drawn into thc burner pipo which i'urthcr insurcs complotc admixturc of the particles oi' oil and cnuscs propcr vapolixation. From the vuporizing chambcr, the oil passes into the burner pipe when it is mixed with air or steam at a high temperature, on other fluid capable oi supporting' combustion and is projected through the nozzle in. a flame.

The operation of the auxiliary burner 37 is identical to the operation oi' the main. burner. The heat generated by the auxiliary burner heats the retort and preheating the chamber to furnish the properly heated Huid and oil to the main burner.

It is to heunderstood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit ot' the invention or the Ascope of the subjoined claims. y

I claim:

LA burner for liquid fuel comprising a burner casing, a burner, pipe arranged in said casing, a retort surrounding a rtion of said easing, a preheater fo' fluid suI-, rounding another portion ,of said casing, m rmentions between said burner pipe, said retort and said preheater, an auxiliary burner arranged in said casing, and connertions between said auxiliary burner, said retort and said preheater.

2. A burner for liquid fuel comprising a e5 casing, a main burner arranged Within said casing, a tubular member surrounding said casing and spaced therefrom to form a retort, a second tubular member surround ing another portion of said casing and spaced loo therefrom to form a preheater -for fluid, pipes connecting said retort and said preheater to said main burner, an auxiliary burner arranged in .said casing, and connections between said pipes and said auxiliary burner. Y'

il. ln burner for liquid fuels, a casing having open ends, a burner pipe arranged in said casing, a retort surrounding a portion oi said easing, a preheater surrounding ani other portion of said casing for preheating fluid to be mixed with said fuel, pipes con necting said retort and said preheater to said burner pipe, an auxiliary burner arranged in said casing, and connections between said pipes and said auxiliary burner.

4. ln a liquid fuel burner, a casing, a main burner pipe, a fuel heating jacket surround 4ingr a portion of said casing, a jet extending partially through said main burner pipe 320 adapted to receive a highly heated fluid to he admixed with the fuel, a i'uel inlet pipe connecting said jacket to said burner ipe in-` termediate the ends of Said burner plpe, and

:in auxiliary burner arranged in said casing to prehcat the fuel in said jacket.

5. A burner for liquid fuels comprisin substantially tubular burner casing havln open ends, a retort surrounding a. portion o said casing, a preheater surrounding another y IEE between said pipes and said auxiliary burner.

In testimony whereof, aix my signa-ture 10 1n presence of two witnesses.
